Hi Michael,To simplify, I'm going to give you the SU2 spec (FP loading will be backwards compatible).First things first : -1000000 means : unknown / unsetPositions : if prefixed by 0 : invalid pos, nothing else on line...Types of wpts :ewptinvalid 0eairport 1ertewpt 2esidwpt 3estarwpt 4eairwaywpt 5, not appearing on rte page, within route segmenteholdwpt 6, off the top of my head, not used anymoreHere goes- id- type of wpt- via- position- if airport : = rnw = departure (0 or 1) = rnw position else = flyover (0 or 1) = is runway extension (0 or 1)- if restriction active (0 or 1) = constrained alt = at or below indicator '-' or 'A' or 'B' = if block, upper alt constraint = constrained IAS- procedure type (following is too complex to go in details, and it's now late, maybe another time)- track or heading- hdg proc from position- proc hdg- proc alt- proc radial- proc distance- proc direct to- left or right turn (unused)- wpt is on missed approach (0 or 1)- wpt is on transition (0 or 1)- wpt is on specific rnw path of a sid (0 or 1)- wpt is on approach path (0 or 1)- hdg to be set after FP is built (0 or 1)- wpt is part of sid (0 or 1)- wpt is part of star (0 or 1)- wpt is part of an approach (0 or 1)- if wpt is a hold fix (0 or 1) = fix id = present position hold (0 or 1) = inbound crs = direction L or R = leg time = leg distance = best speed = constrained speed = constrained altdone..Start of file- origin- number of nodsNow at end of file :- name of sid- name of sid transition- name of star- name of star transition- name of approach- name of approach transition- rnw extension distanceThat's it.Enjoy !Anthony MertonPrecision Manuals Developmenthttp://www.precisionmanuals.com

Hi Anthony,Thanks a bunch this is exactly what I needed. The reason for my question is that I and some friends programmers are thinking of developping an application with a user friendly UI to create, edit, modify terminal prcedures. I believe that with the new syntax for Sids and Stars as well as the precious information you just gave me we will be able to get working. Thanks again.Michael

Hi Anthony,You may remember you wrote the following:>- procedure type (following is too complex to go in details,>and it's now late, maybe another time)Since SU2 has now been released I guess you may have a spare minute now to give us some detailed information on the procedure type.Michael

0 eprocnone, not a procedure wpt1 eprochdgalt, keep hdg until alt2 eprochdgdistance, keep hdg until dist from3 eprochdgdistancealt, keep hdg until alt not before dist4 eprochdgradial, keep hdg until radial 5 eprochdgintercept, keep hdg until intercepting6 eprocvectors keep hdg until ATC directionsThe above can be keep track also.hope this helpsanthonyAnthony MertonPrecision Manuals Developmenthttp://www.precisionmanuals.com

Hi Anthony,Thanks for your reply. Just found it. It was buried on page 9 of the forum due to all these posts relating to the download of SU2.This is exactly what we wanted to know. Thanks again.Michael
